So after the base coat of Dawnstone, I gave these Marines a wash - a mix I made that is 4 parts Lahmian Medium, 1 part Nuln Oil and 1 part Agrax Earthshade (the older, pre-2022 versions of those shades). Here they are after applying this custom shade:

Now I begin the slightly fiddly and time consuming process of panel lining with Nuln Oil:

Finally, I wrote about them having red helmets in my previous entry - here are the results of some tests: firstly, just Blood Angel contrast over grey (too dark I felt). Then Blood Angel Contrast over white with Wildrider Red highlight and Carroburg Crimson recess shade - again, I felt these looked too dark/grimy, especially against the grey of the rest of the armour. So I tried Baal Red Contrast over a base of Wildrider Red (again, but dark than I'd have liked), which brought me to the final method I'm going to use: Baal Red Contrast over white, Carroburg Crimson recess shade, and tidy up highlights with Wildrider Red where necessary:

Next, I'll be continuing with panel lining, more pics soon..!
